Low vitamin D levels, certain infections, and specific dietary habits may increase the risk of developing neuromyelitis optica spectrum disorder (NMOSD). That’s according to the findings of a systematic review that analyzed data from 50 studies involving more than 21,000 people worldwide. Certain modifiable factors, such as diets high…

People having area postrema syndrome (APS), that is, uncontrollable nausea, vomiting, or hiccups, as the first symptom of neuromyelitis optica spectrum disorder (NMOSD) are more likely to relapse sooner and more frequently than those having another first symptom. These are the main findings of a single-center study that retrospectively…

Certain long non-coding RNAs (lncRNAs) — a family of molecules that can regulate gene activity — tied to immune function were at significantly higher levels in the blood of people with neuromyelitis optica spectrum disorder (NMOSD) compared with the general population, a study reports. All four evaluated markers —…

The rate of disease onset or relapse of neuromyelitis optica spectrum disorder (NMOSD) after a SARS-CoV-2 infection — the virus that causes COVID-19 — is extremely low, at about 1 in 50 million, according to a worldwide review study. The occurrence of NMOSD was even lower, at 1 in…

The risk of neuromyelitis optica spectrum disorder (NMOSD) attacks following vaccination is low, and such attacks have not been found to be associated with any particular type of vaccine, according to a review study. Also, post-vaccine attacks tended to happen more frequently in men, patients negative for antibodies against…

People who develop neuromyelitis optica spectrum disorder (NMOSD) later in life may go on to experience worse outcomes than those who have early-onset disease, a study in China has found. Worse outcomes included a higher frequency of inflammation of the thoracic spinal cord during relapses, more brain lesions and…

The onset of neuromyelitis optica spectrum disorder (NMOSD) at an older age is linked with a greater likelihood of spinal cord involvement at the first disease attack, fewer relapses, and greater disability, according to a study in China. “Age of disease onset correlates with clinical characteristics and prognostic outcomes…

The first three months after giving birth are a particularly high-risk time for developing neuromyelitis optica spectrum disorder (NMOSD) and for experiencing relapses when the disease is already established, an expert emphasized in a recent webinar hosted by the The Sumaira Foundation for NMO. The pregnancy-focused webinar featured…
